(Maybe) the Loudest exhaust in the world, by not having one in the first plac

Ever wondered what the V8 M3 sounds like without an exhaust? Thatís what I went to find out today while taking the Supersprint Race off the car. Started her up without the back box (muffler, axle-back, auspuff, rear section) and the results are amazing!

Itís ridiculously loud as expected in terms of volume, but I was pleasantly surprised that the tone characteristic sounded rather nice. I just wish I could run the car like that. Cheaper than any after market exhaust out there in the world and it saves a ton of weight at the same time.

The OEM exhaust is mega heavy!

The primary catalytic converters are still there; the secondary cats and resonators have been removed previously. So the sound you hear is pretty much a cat back straight pipe. Love it!

I did eventually put the original exhaust back on to the car before I left just so you know.
